The problem of mutual coupling between two parallel thin linear antennas in chiral medium is addressed in this article. Expressions for self‐ and mutual impedances are presented. The effect of chirality of the radiating medium on the mutual resistance and reactance is discussed. It is found that with proper choice of parameters the chirality of the medium may considerably reduce the mutual impedance effect. Also discussed is the role of chirality on the projected values of the self‐ minus mutual resistance of the antenna, which is important in antenna array design. It may be concluded that under certain conditions the self‐ minus mutual resistance is considerably smaller than in the achiral case, so that an array made with chiral antenna elements may produce higher gain.
